Is is ever possible that God would allow you to actually see your Guardian Angel? And, have any Saints ever seen their Guardian Angel and has anyone reading this ever encountered their guardian angel in that way?
Yes. Padre Pio and if I remember correctly, St Gemma Galgani saw them as well. If you use the search engine on CAF, you should be able to find the answers to your other questions.
St. Catherine Laboure asked her Guardian Angel to obtain for her the favor of seeing the Blessed Mother… and he accompanied her to meet the Blessed Mother.
